Question

5. What is a trapezium? When do you call a trapezium an isosceles trapezium?​

Answer 1

Answer:

• A trapezium has only one pair of parallel sides. A trapezium is said to be an isosceles trapezium if its non-parallel sides are equal.

• A quadrilateral in which one pair of opposite sides is parallel is called a trapezium. If the non-parallel sides of a trapezium are equal, the trapezium is called an isosceles trapezium.

• In Euclidean geometry, a convex quadrilateral with at least one pair of parallel sides is referred to as a trapezium in English outside North America, but as a trapezoid in American and Canadian English.

• Area: ½ x (sum of the lengths of the parallel sides) x perpendicular distance between parallel sides

• Perimeter: sum of lengths of sides of trapezoid

• Number of vertices: 4

• Number of edges: 4

• Properties: Convex polygon

• Type: Quadrilateral

• Line of symmetry: 0

• A quadrilateral having one and only one pair of parallel sides is called a trapezium.

• A trapezium is called an isosceles trapezium if its non parallel sides are equal.

• Trapezium is a quadrilateral with four sides.

• If the non parallel sides are of equal length, then it will become an isosceles trapezium.

• A trapezium is a figure in which a pair of opposite sides are parallel. a trapezium is called an isosceles trapezium If the non parallel sides are equal.

• Trapezium --- A quadrilateral having exactly one pair of parallel sides is

called a trapezium.

• Isosceles Trapezium --- A trapezium is said to be an isosceles trapezium if its non - parallel sides are equal.

Answer 2

Answer:

Trapezium

A quadrilateral having one and only one pair of parallel sides is called a trapezium.

A trapezium is called an isosceles trapezium because of its nonparallel sides are equal.
